Quoted from DnDPins:I should clarify the problem
When I test in single lamp mode:
1) Row 3 lamp 13 and Row 4 lamp 14 each light together
2) This repeats for every lamp on both rows
A visual inspection of each of the connectors and wiring to the lamp sockets does not show any obvious shorting. (It is very difficult to access / see the WOW light and Ringmaster light board)
What is the best way to troubleshoot next?
Hold up - each row/col only has eight lamps on it. Are you meaning:
When light 13 (col 1, row 3) is on, so is lamp 14 (col 1, row 4)?
